@PeterTurner Yes, I agree that using the term "unreformed" would be confusing at best. I'm not sure what you'd be referring to. If you said "non-reformed" I'd take that as "Protestant, non Calvinist" with the assumption that fringe sects (e.g. JW, LDS) are excluded too.
@DanAndrews I don't think that's what it's saying at all. Everyone has faults. In the metaphor that Jesus provides, your neighbor has a sliver in his eye, but you have a plank. Both are wood.
Consider Matthew 18, which is a clear protocol for addressing sin in the Church.
There's a very clear assumption that legitimate sin must be addressed. Now if someone is lustful, having his sin addressed by another who fornicates would be utterly useless.
Since you did not specify a denomination that you preferred an answer from I will simply point to a part in the Bible that I think is self explanatory. Whether a certain Christian group will follow it or not is a different story entirely.
This is best answered by Matt. 18 starting vs. 15. Simply...
However, another may struggle with smoking (since I guess you think that's a sin), but that is irrelevant when he admonishes the lustful believer unto repentance.
@waxeagle I mean the part about reformed being synonymous with Calvinist. I always figured the word had something to do with the entire reformation, not just one hunk of it.
@PeterTurner In a broad sense, he's right. Generally you won't hear Protestants using the word "reformed" except in reference to Calvinists, although sometimes you'll see someone who identifies as a reformed Arminian.
On the other hand, if you google Reformed Lutheran, you'll get a bunch of "Reformed vs. Lutheran theology" pages.
@PeterTurner "Reformed" by itself now means "Calvinist", and is probably the better term because "Calvinists" like Zwingli were active before Calvin himself
@fredsbend Not really. I started writing a paragraph or two for Part 1: Coordinates and Lines, then realized that it was going to be a full post on it's own, so I changed it to Part 0: Introduction. :P
